The lowest point in Bob Litwin's life prompted the most profound change.

Litwin, a former ITF senior world No. 1 and long-time performance coach, was mourning the death of his partner of 28 years, Carol, hobbled by a failed hip surgery and stricken by a debilitating depression when he looked in the mirror one morning and had a epiphany.

Litwin realized he needed a new life story and set out to live it.

The power of narrative as an agent of change is the focus of the author's new book, Live the Best Story of Your Life: A World Champion's Guide to Lasting Change.

"Where therapy fails, this brand of storytelling is a faster, more effective way to lasting change," Litwin writes. "Live the Best Story of Your Life does not shift what you do, it shifts who you are. I have been coaching for over 40 years using this simple method. Now I am going to share with you the secret sauce so that you can do it on your own."

Litwin says profound life change can come from creating your own life narrative.

"It's simple: Know where you are starting. Decide where you want to go," Litwin says.

The book includes not only the simple two-step method, but also 33 private coaching sessions that will help you stay in the game of change.
